I'm just curious about what NTP means. I'm guessing that it is "No Time Predicted"? We flew on Southwest last week. Before we left for the airport, we checked the flight status, and saw that our flight was delayed. It showed a new departure time one half hour later than the scheduled time, and also showed "NTP." We took our time getting to the airport. When we got to the gate, the board showed our flight as "delayed" with no scheduled time. Fifteen minutes before the original departure time, they began boarding, and the plane left at the scheduled time. We were glad that we hadn't dawdled too much!
